To all whom it may concern."

Be it known that I, DANIEL McEnLANn, a citizen of the United States,residing at Mankato in the county of Blue Earth and State of Minnesota,have invented new and useful Improvements in Ventilating Boots andShoes, of which the following is a specificationt.

The device forming the subject matter of this application is adapted tobe employed for ventilating articles of footwear.

The invention aims so to construct an upright air passage in the leg andin the foot of an article of footwear, that the lower end of the passagewill not be distorted as the foot of the wearer is crowded backwardly-inwalking.

Another object of the invention is to pro vide means whereby theentrance of dirt into the lower end of the passage will be avoided, theconstruction being such that am may readily pass into the interior ofthe article of foot wear from the lower end of the passage.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of thelnvention.

In the accompanying drawings Figure 1 shows in side elevation, anarticle of foot wear embodying the present invention;

Fig. 2 is a vertical section showing an articleiof foot wear wherein thepresent invention is embodied;

3 is a top plan of the structure shown in Figs. 1 and 2; and

there is provided an article of footwear includlng a leg S, and a foot Thaving an ele-' vated instep R. A strip M is applied to each side of theleg S, on the interior of the leg, the strip extending downwardly to thefoot T. The strip M forms a passage (1. The passage a is forwardlyinclined toward the toe U of the foot T to prevent a distortion of thelower end of the passage a as the foot of the wearer crowds backwardlyin walking. The upper end of the passage a is open as indicated at b.The lower end of the passage a terminates directly above the instep R topermit the pumping of air into and out of the passage a as the instep ofthe wearer yields. The lower end of the passage 0: is open as indicatedat c. 7

Having thus described the invention, what is claimed is An article offootwear comprising a leg and a sole; and a single-layer tape-like stripof material formed separately from the leg 7 and extended downwardlyalong the inside of the leg, the longitudinal edges of the strip beingsecured to the leg and the transverse end edges of the strlpibeingspaced from the leg to form an air passage which is open axially at itsends, the lower end of the stri being spaced above the upper surface oft e sole.

In testimony that I claim the foregoing as my own, I have hereuntoaffixed my signature in the presence of two witnesses.
